What action should be taken if re-ignition occurs after a Type B extinguisher is used?

When dealing with a fire that has the potential to reignite after using a Type B extinguisher, the best action is to attempt to extinguish it again. Type B extinguishers are specifically designed for flammable liquids, such as gasoline, oil, and solvents, which can reignite if not completely extinguished.

If re-ignition occurs, it indicates that there may still be residual material that could catch fire again. Therefore, remobilizing the extinguisher to address the fire promptly is essential to prevent it from escalating. It's important to have a proper technique and ensure that the base of the fire is targeted effectively.

In contrast, simply evacuating the area, assessing the environment, or waiting without taking action could provide an opportunity for the fire to grow larger and more dangerous. Engaging again with the Type B extinguisher supports the goal of fully eliminating the hazard in the safest manner possible.
